With heart failure, the heart is unable to pump the right amount of blood throughout the body. This causes blood to back up in the veins. It can lead to a buildup of excess fluid in the lungs, feet, and elsewhere. Heart failure can worsen with time. Vital organs can be damaged from low blood flow. Doctors are often aggressive in treating heart failure to try to prevent worsening and damage to other organs.

The leading causes of heart failure are:
Other common causes include:
Other less common causes include:
Heart failure is more common in older adults. Other things that increase the risk of heart failure include:
Heart failure can cause:
The doctor will ask about symptoms and past health. A physical exam will be done. The doctor may note changes caused by heart failure such as fluid build up in legs. They may also hear abnormal sounds when they listen to the heart. Blood tests may be done to look for certain markers of change in the heart.
Tests can help to show what areas of the heart are affected. They can also show changes in blood flow. This can be done with:
Doctors will use the test results to determine level of heart failure. This will help guide treatment plan.
Heart failure will need lifelong care. The goal is to prevent worsening of symptoms. Treatment can ease symptoms and improve quality of life. Some may also have some improvement in heart strength.
Treatment will vary by person and over time. A care plan will require input from patient and care team. Tracking weight and symptoms everyday will help to catch changes early. Fast treatment of changes may reduce worsening and other problems.
Heart failure may be caused by another health issue. Treating this issue may improve heart failure or prevent it from getting worse. For any form of heart failure, treatment may include:
Medicine can help to ease workload on the heart. They may include:
Medicine may also be give to treat other heart issues like high blood pressure or high cholesterol.
Day to day habits can affect heart health. Some changes may help ease stress on the heart. Changes may include:
Heart failure may cause or be worsened by rhythm problems of the heart. A defibrillator or pacemaker may be implanted. They give electrical shocks if the heart starts dangerous rhythms.
Other devices can help support the heart. They may be needed short term to help recover from an injury or illness. They may also support the heart in last stages of heart failure until a transplant can be done. These devices increase the amount of blood pumped to the body without increasing workload on the heart. Examples include:
A heart transplant may be needed for severe heart failure, if all other treatment has failed.
The best way to prevent heart failure is to reduce your risk of heart disease, high blood pressure, and diabetes. General steps include:
